Edit: Does anyone else see the benefit of death clerics? Free doubled Chill touch against adjacent targets plus the rider is actually good against armies that would otherwise be using second wind/healing word. Toss in some sanctuary or other buffs during approach and you have a nasty bite.
There are plenty of cleric specializations that get martial weapon proficiency, and the elven races can give it as well. Thing is, any reasonable leader builds an army based on who he is most likely to fight.
I am the flush of excitement. The blush on the cheek. I am the Rouge!
